Title: High-speed ttl buffer circuit and line driver
Inventor: RAASU JII JIYANSON
IPC: H03K19/088
Filed: 1991-06-19
Abstract: PURPOSE: To increase the switching speed by settling an input threshold voltage level required for switching an input transistor TR circuit by a clamping circuit simultaneously with clamping of a base node to a low potential level. CONSTITUTION: When a signal in the low potential level appears in an input terminal Vin, an input TR element Q1 is turned off to supply it to an emitter follower TR element Q2. The initial high voltage level of the element Q2 is supplied to a phase splitting TR element Q3, and a quick switching operation is started. When the potential level in the collector node of the element Q3 falls more than the high potential level in the base node of the element Q2, the base driving current shunted to the collector node of the element Q3 is made conductive. Second clamping circuits D4 and D5 clamp the potential level in the collector node of the element Q3 to limit a threshold saturation operation area.

Filed: 1990-06-29
Abstract: PURPOSE:To obtain a semiconductor storage device having a strong latchup by widening an N<+> type diffused layer connected to a power source voltage and providing a distance from a second gate. CONSTITUTION:Since a field 2 connected to a power source voltage Vcc is widely formed, a resistance component is formed at the field 2 connected to the voltage Vcc to absorb a trigger applied to a power source voltage Vcc pin thereby to prevent punchthrough to aluminum, thereby improving latchup resistance. Thus, the field 2 connected to the voltage Vcc is increased to increase a distance of a contact to a second gate 4 to provide a resistance component, thereby absorbing a trigger applied to the pin. Thus, latchup resistance of the pin is improved.

IPC: H04B7/005
Filed: 1980-12-08
Abstract: PURPOSE:To reduce power consumption without giving unnecessary interruption to a base station, by providing a means which variably controls transmission power continuously in response to a reception input electric field strength at a mobile station. CONSTITUTION:Electromagnetic waves transmitted from a base station (not shown) are received at an antenna 1 of a mobile station and converted into intermediate frequency at a mixing and local oscillator 3 via a common use device 2, amplified and demodulated at an IF amplification demodulator 4 and given to a receiver 5. On the other hand, a part of the intermediate frequency signal obtained at the said mixing and local oscillator 3 is applied to an electric field detector 12, and the circuit 3 generates a DC voltage depending on the received intensity. Further, this DC voltage is applied to a power controller 13 provided between a transmission power amplifier 11 and a modulation/multiplier 9 as a control voltage. Thus, the power transmitted from the antenna 1 to the base station is controlled smaller as the received intensity is greater, and transmission with unnecessary power can not be made to the base station.
